disassembling position (as shown in FIGS. 10 and 11), an unlocked
position (as shown in FIG. 12) and a locked position (as shown in
FIG. 13); when the main body 2 rotates to the disassembling
position, the protrusive block 42 corresponds to the slide slot 41
in the axial direction 11 to extract the main body 2 from the
sleeve member 1; when the main body 2 rotates to one of the locked
position, the unlocked position and the disassembling position, and
the elastic abutting member 32 is engaged within one of the three
recesses 12; when the elastic abutting member is engaged within one
of the three recesses 12, a vibration transmitted from the key and
an impact sound of the elastic abutting member 32 can inform a user
that the main body 2 has been rotated to one of the locked
position, the unlocked position and the disassembling position.
Given the above, when the main body rotates to make the protrusive
block axially corresponds to the slide slot, the main body can be
inserted into or pulled out from the sleeve member, so the main
body can be replaced without the sleeve member and the object being
disassembled together. In addition, when the hook is engaged with
the slot, the main body and the engaging member can be fixed to and
comove with each other, and the engaging member can comove with the
main body to detach from the sleeve member so that it is more
convenient for disassembling and replacement.
While we have shown and described various embodiments in accordance
with the present invention, it should be clear to those skilled in
the art that further embodiments may be made without departing from
the scope of the present invention.
